Kevin’s Angle

What it Measures

Angle of bisection of plantar calcaneus line drawn to most deviated bisection point of the achilles tendon.

Significance

  • Moderate significance
  • High significance above 12°

Kevin’s Angle

About

Kevin’s Angle is another measurement and the final test in the BIQ 10 exam. Kevin’s Angle is an alternative to measuring the bisection of the calcaneus. Kevin’s Angle is restricted to measuring the distal Achilles near the insertion and the Achilles proximal and posterior to the ankle. Kevin’s Angle is a measurement that is easy to perform and clear to observe since it does not require a direct bisection calcaneus and only requires finding a relative bisection of the Achilles. The Achilles can be used to find an approximation or estimation of the degree of eversion or inversion in the calcaneus.

Effect of Deviation

This is a sign used to help determine the rear mid and forefoot compensatory strategies when anatomy is less efficient for normal gait
